U can only choose the price. We were lucky cos there's no normal 13nett prawns, so I actually got the 20nett deep sea prawns instead. The highest price is 28 which are the same prawns but larger
Pig skin has good texture but the braise is weak.
The dry one is not recommended, cos the sambal is v avg
Honestly the big prawns don't taste too much better than the smaller prawns. It just tastes different, so unless you're a prawn connoisseur it really is not too worth it
